Collecting examples of good storytelling

My friend and I are working on a new product + platform in the wireless presentation space and I need to finish up the semester’s work by creating concept boards. I would love to do a quick video to explain the product but besides the time involved in creating them, I’d like a more portable way of describing our 3 concepts in this space.

Do any of you have suggestions or examples of places where you’ve seen a product explained clearly and concisely? If so, please post in the comments as I’m sure other would like to know.
